Preheat the oven to 325 degrees F and lightly spray 9x5 loaf pans with non-stick spray. Set aside.
Peel your apples and dice into small pieces.
In a medium bowl, add the flour, cinnamon, nutmeg, baking soda, and salt and whisk together.
In another large bowl, add the applesauce (or vegetable oil), eggs, sugars, and vanilla and mix with a whisk until fully combined.
Pour the dry ingredients into the wet ingredients in batches (three parts) and stir with a spatula until fully combined. The batter will be very thick.
Stir in diced apples.
Pour half of the batter into each prepared loaf pan - try to keep the amounts even.
